RecallDeck - Flashcards

Streamline daily tracking and management with RecallDeck 暗記カード. Core features work offline, no account required.

RecallDeck is a spaced repetition flashcard app that works out of the box. Make cards, review daily, watch your streak grow — no settings to study and no subscription to manage. Every feature is free, with no cap on decks or cards.

Scientific scheduling, zero configuration • Built on the open FSRS spaced repetition algorithm: after each rating, the next review is scheduled right before you would forget • Four rating buttons (Again / Hard / Good / Easy) with the next interval shown on each button • Missed cards come back in ten minutes; clear the queue and you are done for the day

Fast card creation • Continuous input: the form clears and refocuses after every save • Bulk import: paste multiple lines, one card per line, preview, done • Attach an image to either side; one toggle creates a reversed twin card

Progress you can see • 12-month review heatmap and current streak • 30-day due forecast and average recall rate

Syncs across your devices, no account needed • Your cards sync across your own iPhones through your own iCloud • Optional daily reminder and badge with today's due count

Creating cards, reviewing and stats all work offline. The only thing that needs a connection is a single banner at the bottom of the screen. If you'd rather not see it, you can remove it from Settings — that hides the banner and nothing else, because decks and cards are already unlimited.

No tracking, and no ATT prompt. Your cards never leave your device and your own iCloud.
